The alternative of passing an object template at context creation is
unfeasible because we need a context to instantiate the template.
At the time we create the context from snapshot or bootstrap from
scratch, we would already need that template instance, leading to a
chicken-and-egg problem.
This is an alternative that is simpler and less intrusive.

Let x be a fulfilled promise and y be another promise. |x.then(() => y)|
should call |y.then|, but the current implementation calls PromiseChain.
We can see the difference when we set a custom function to |y.then|.
This CL fixes the spec violation, but as a result |then| is no longer
a wrapper of |chain| and in some cases it does not work well with
|accept| or |chain|. That is not a problem for ES6 promise users because
ES6 promise doesn't have them.

Up until now we can only inline based on JSFunction, because of the way
the deoptimization works. With this change we will be able to inline
based on the SharedFunctionInfo and materialize the JSFunction from a

This change rewrites regexps like (ab|ac|z|ad|ae|af) into (a[b-f]|z). We can only reorder disjunctions like this for case-dependent regexps. For case-independent regexps, the disjunctions should be pre-sorted for best results.

The initial implementation of this method takes a couple shortcuts:
- At some points in the spec, we should be making a reference to
"Table 49" and instead do property lookup on the constructor.
This is an issue with some other TypedArray methods too.
- The spec indicates that, if constructor and @@species haven't been
messed with in particular ways, then there should be a memcpy
from the old to the new. That fast path is not implemented here
in this patch, but because V8 doesn't canonicalize NaN, the result
isn't observably different.
